In order to solve the technical problems, the embodiment of the invention provides a voice control method, a device, equipment and a storage medium for a steering wheel of a vehicle, which are used for receiving voice instructions, identifying the voice instructions, generating operation instructions, sending the operation instructions to a motor, and controlling the steering wheel to rotate by the motor according to the operation instructions.

For ease of understanding, the following describes the voice control method of the vehicle steering wheel in detail with reference to the accompanying drawings.
Fig. 1 is a flow chart of a voice control method of a steering wheel of a vehicle according to an embodiment of the present invention.
The method comprises the following steps:
s1, receiving a voice instruction to be recognized;
in the embodiment of the invention, in order to realize interaction between a person and a steering wheel, electronic equipment (hereinafter referred to as the electronic equipment) for executing the method can be installed in the steering wheel of the passenger car. The voice command to be recognized is a rotation command sent by a driver to the electronic device through voice, and in practical application, the rotation command may be a left rotation angle of 500 °, a right rotation angle of 600 °, a rotation angle speed of 100 degrees per second, and the like, which is not particularly limited.
S2, recognizing the voice command to be recognized, and generating an operation command.
In the embodiment of the invention, in order to realize better interaction between a person and a vehicle, after receiving a voice command to be recognized sent by a driver, the voice command to be recognized is first recognized, and then an operation command is generated based on the recognition result of the voice command to be recognized, wherein the operation command is a command for controlling the motor to run, for example, controlling the motor to rotate forward, rotate backward and the like, and the invention is not particularly limited.
The specific process of recognizing the voice command to be recognized will be described later, and will not be described in detail here.
And S3, sending the operation instruction to a motor so that the motor controls the steering wheel based on the operation instruction.
In the embodiment of the invention, in order to control the rotation of the motor, the motor is communicated with the motor, an operation instruction is sent to the motor, and the motor controls the rotation of the steering wheel of the passenger car according to the operation instruction after receiving the operation instruction.
In practical application, the rotating direction and the current of the motor can be controlled through PID, so that the steering wheel of the passenger car reaches the target rotating angle and the target rotating angle speed.
In the embodiment of the invention, the voice command is received, the voice command is identified, the operation command is generated, then the operation command is sent to the motor, and the motor controls the steering wheel to rotate according to the operation command; the steering wheel can be controlled through voice instructions without manual operation of a driver, so that the workload of the driver is reduced, and intelligent steering is realized.
Fig. 2 shows another voice control method of a steering wheel of a vehicle. As shown in the figure 2 of the drawings,
in the embodiment of the invention, the steering wheel of the passenger car has two working modes, namely a manual control mode and a voice control mode. In actual work, a liquid crystal display screen can be arranged on a steering wheel of the passenger car, and a driver can select a manual control mode or a voice control mode through touch of the liquid crystal display screen to switch the manual control mode and the voice control mode; or the driver directly rotates the steering wheel by hand and can also automatically exit the voice control mode to switch to the manual control mode.
In practical application, the liquid crystal display can also display the rotation condition of the steering wheel and whether the steering wheel is in a zero position, so that a driver can check the steering wheel at any time.
When the passenger car is started, the working mode of the steering wheel defaults to a manual control mode; in the manual control mode, the rotation of the steering wheel of the passenger car cannot be controlled through a voice command, the motor carries out speed-following power assistance according to the manual stirring of the steering wheel, and meanwhile, a rotation angle sensor and a rotation speed sensor in a steering system feed back the real rotation angle and the real rotation angle speed of the steering wheel detected in real time to the electronic equipment and display the real rotation angle and the real rotation angle speed on a liquid crystal display screen in real time; the target steering angle and the target steering angle speed of the steering wheel can be displayed on the liquid crystal display screen at the same time.
After the passenger car is started, a driver can select a voice control mode through touch operation of the liquid crystal display screen, and at the moment, the voice control mode is activated. In practical application, when a voice command to be recognized is received, whether the voice command to be recognized is sent by a driver or not should be judged first; then, in some possible embodiments, the method further comprises:
judging whether the voice command to be recognized is sent by a driver or not;
if yes, executing the steps of identifying the voice instruction to be identified and generating an operation instruction;
if not, the flow ends.
It can be understood that whether the voice command to be recognized is sent by the driver can prevent people except the driver from sending the voice command to be recognized to the electronic equipment on will, and driving safety is ensured. In practical application, any method may be used to determine whether the voice command to be recognized is issued by the driver, for example, the voice command to be recognized is compared with voiceprint, and the like, which is not limited in detail. In some possible embodiments, determining whether the voice command to be recognized is issued by the driver includes:
extracting voiceprint features to be recognized of a voice command to be recognized;
matching the voiceprint features to be identified with preset voiceprint features in a prestored voiceprint library;
if the voice print library has preset voice print characteristics matched with the voice print characteristics to be identified, judging that the voice command to be identified is sent by a driver, executing the voice command to be identified, and generating an operation command;
if the preset voiceprint features matched with the voiceprint features to be identified do not exist in the voiceprint library, the voice command to be identified is judged not to be sent by a driver, and the process is ended.
In order to determine whether the voice command to be recognized is issued by the driver, a voiceprint library including voiceprint features of all drivers of the passenger car may be stored in advance in the present electronic device. After receiving the voice command to be recognized, matching the voiceprint features of the voice command to be recognized with the voiceprint features stored in the voiceprint library. Voiceprints refer to the spectrum of sound waves carrying speech information displayed by an electroacoustical instrument, and the characteristics of the voiceprints include tone, duration, intensity, pitch and the like. In order to facilitate distinguishing description, voiceprint features of the semantic instruction to be identified are defined as voiceprint features to be identified, and voiceprint features in a voiceprint library are defined as preset voiceprint features.
The corresponding relation between the preset voiceprint characteristics and the driver exists in the voiceprint library, namely, the corresponding voiceprint characteristics can be found in the voiceprint library by the voices of all drivers of the passenger car. In practical application, the voiceprint library can be established by training a neural network model. The voice print characteristics of all drivers of the passenger car are extracted in advance to serve as training data, and the drivers corresponding to the voice print characteristics are respectively used as training labels to train the neural network, so that a voice print characteristic model is obtained; the pre-extracted voiceprint features of all drivers of the passenger car are the preset voiceprint features. After receiving the voice command to be recognized, extracting the voice command to be recognized voice feature to be recognized, inputting the voice feature to be recognized into the voice feature model, and outputting a driver corresponding to the voice feature to be recognized if the voice feature to be recognized can be successfully matched with the preset voice feature.
In order to judge whether the voiceprint feature to be identified is the voiceprint feature of the passenger car driver, matching the voiceprint feature to be identified with preset voiceprint features in a voiceprint library; if the voice print feature to be identified can be successfully matched with the preset voice print feature, judging that the voice print feature to be identified is the voice print feature of the driver, sending the voice command to be identified to the driver, determining which driver sends the voice command to be identified according to the corresponding relation between the preset voice print feature and the driver, and executing the steps of identifying the voice command to be identified and generating the operation command. If the voice print feature to be identified cannot be successfully matched with the preset voice print feature in the voice print library, judging that the voice print feature to be identified is not the voice print feature of the passenger car driver, and if the voice command to be identified is not sent by the driver, executing no step of identifying the voice command to be identified and generating an operation command, and ending the flow.
It can be understood that based on the comparison of the voice print characteristics to be identified and the preset voice print characteristics in the voice print library, whether the voice command to be identified is sent by a passenger car driver or not can be judged, the voice command to be identified is prevented from being sent to the electronic equipment by people except the driver along with intention, and the driving safety is ensured. In practical application, after confirming that the voice command to be recognized is sent by a passenger car driver, the voice command to be recognized needs to be further recognized; then, in some possible embodiments, identifying the voice instruction to be identified, and generating the operation instruction includes:
identifying the voice command to be identified and generating text information corresponding to the voice command to be identified;
and generating an operation instruction according to the text information.
In order to further execute the voice command to be recognized, the voice command to be recognized needs to be recognized, text information corresponding to the voice command to be recognized is generated, and then an operation command is generated according to the text information. The operation command is a command for controlling the operation of the motor, for example, controlling the forward rotation, the reverse rotation, etc., and is not particularly limited.
It can be understood that the voice command to be recognized can be converted into the operation command for the motor by recognizing the voice command to be recognized, generating text information corresponding to the voice command to be recognized and generating the operation command according to the text information, so that the control of the voice command on the steering wheel is realized. In practical application, the voice command to be recognized can be recognized in any mode, and text information corresponding to the voice command can be generated; in some possible embodiments, identifying the voice command to be identified and generating text information corresponding to the voice command to be identified includes:
identifying a feature vector to be identified contained in the voice command to be identified;
matching the feature vector to be identified with a preset feature vector in a pre-stored feature library;
and generating text information corresponding to the voice instruction to be recognized based on the matching result.
In order to identify the voice command to be identified, the feature vector included in the voice command to be identified may be first identified, and based on the purpose of identifying the feature vector included in the voice command to be identified, a semantic library including the feature vector may be stored in advance in the present electronic device. In practical applications, the feature vectors may include, but are not limited to, isolated words, connective words, keywords, and the like. In order to facilitate distinguishing description, feature vectors contained in the voice command to be recognized are defined as feature vectors to be recognized, and feature vectors contained in the semantic library are defined as preset feature vectors.
In practical application, in order to improve the probability of correct recognition, for the same feature to be recognized, a plurality of preset feature vectors containing keywords may be set in a feature library, and language features of different languages or different dialects are considered. For example, the setting of the left steering angle of the steering wheel may use a plurality of preset feature vectors, such as "left turn XXX/steering wheel left turn XXX/set steering wheel left turn XXX … …", which are not particularly limited.
The corresponding relation between the preset feature vector and the text information exists in the feature library, and in practical application, the feature library can be established by adopting a mode of training a neural network model; extracting feature vectors in advance as training data, and training the neural network by taking text information corresponding to all the feature vectors as training labels to obtain a feature model; the pre-extracted feature vector is the preset feature vector. When the feature vector to be identified is input into the feature model, a preset feature vector with the highest similarity with the feature vector to be identified can be determined, and then text information corresponding to the preset feature vector is output.
In order to generate text information corresponding to the voice command to be recognized, matching a feature vector to be recognized contained in the voice command to be recognized with a preset feature vector in a semantic library; and obtaining a preset feature vector corresponding to the feature vector to be recognized according to the matching result, and obtaining text information corresponding to the voice instruction to be recognized based on the corresponding relation between the preset feature vector and the text information in the feature library.
It can be understood that by identifying the voice command to be identified and obtaining text information corresponding to the voice command to be identified, the accurate operation command can be generated. In practical applications, the voice command to be recognized may include various desired operations on the steering wheel, for example, 300 ° left turn, 400 ° right turn, 300 ° rotation speed per second, and the like, which is not particularly limited. Then, in some possible embodiments, the text information includes a target rotation angle and a target rotation angle speed;
generating an operation instruction according to the text information, wherein the operation instruction comprises the following steps:
receiving an actual rotation angle and an actual rotation angle speed;
performing difference operation on the target rotation angle and the actual rotation angle to obtain a rotation angle difference value, and performing difference operation on the target rotation angle speed and the actual rotation angle speed to obtain a rotation angle speed difference value;
and generating an operation instruction based on the rotation angle difference value and the rotation angle speed difference value.
In order to generate an operation instruction according to a target rotation angle and a target rotation angle speed, based on the received actual target rotation angle and target rotation angle speed, performing a difference operation on the target rotation angle and the actual rotation angle to obtain a rotation angle difference value, and performing a difference operation on the target rotation angle speed and the actual rotation angle speed to obtain a rotation angle speed difference value; and generating an operation instruction according to the corner difference and the corner speed difference, wherein the operation instruction comprises the corner difference and the corner speed difference, and the motor rotates according to the corner difference and the corner speed difference so as to drive the steering wheel to rotate.
In practical application, the angle range of the steering wheel of the passenger car can rotate is [ -1000 degrees, +1000 degrees ] ], namely the target angle range can be [ -1000 degrees, +1000 degrees ] ], and the angle value is negative, which indicates that the steering wheel is driven to the left; the angle value is positive, indicating that the steering wheel is driving to the right. The larger the range of steering wheel rotatable angular speeds is [0 °/s,500 °/s ], i.e., the target angular speed range can be [0 °/s,500 °/s ] values, the faster the steering wheel rotates.
It can be understood that the difference value operation is performed on the target rotation angle and the actual rotation angle, the difference value operation is performed on the target rotation angle speed and the actual rotation angle speed, and the operation instruction is generated based on the rotation angle difference value and the rotation angle speed difference value, so that the motor can rotate more accurately, and the passenger car steering wheel is driven to reach the target rotation angle and the target rotation angle speed.
After receiving the operation instruction, the motor rotates according to the operation instruction, so as to drive the steering wheel to rotate; when the actual turning angle of the steering wheel reaches the target turning angle and the actual turning angle speed of the steering wheel reaches the target turning angle speed, the motor stops rotating; if the actual turning angle of the steering wheel does not reach the target turning angle or the actual turning angle speed of the steering wheel does not reach the target turning angle speed, the motor continues to rotate to drive the steering wheel to rotate until the steering wheel reaches the target turning piece and the target turning angle speed, and the motor stops rotating.
Fig. 3 shows a hardware architecture diagram, and fig. 4 shows the working principle of the hardware architecture in fig. 3. As can be seen from fig. 3 and 4, the voice control method of the vehicle steering wheel in the above embodiment can be implemented by the hardware architecture shown in fig. 3.
A liquid crystal display module is arranged on the surface of a steering wheel of the passenger car, and a voice input module, a voiceprint recognition module, a voice recognition module and an electronic control module are arranged in the steering wheel; the liquid crystal display module can display the actual rotation angle and the actual rotation angle speed of the steering wheel.
After the voice control mode is started, the voice input module receives a voice command to be recognized, then the voice command to be recognized is sent to the voiceprint recognition module, the voiceprint recognition module judges whether the voice command to be recognized is sent by a driver, and if the voice command to be recognized is sent by the driver, the voiceprint recognition module sends the voice command to be recognized to the voice recognition module.
The voice recognition module performs recognition analysis on a voice command to be recognized to obtain a target corner and a target corner speed, then sends the target corner and the target corner speed to the electronic control module, and the electronic control module can receive the actual corner of the steering wheel sent by the corner sensor and the actual corner speed of the steering wheel sent by the rotating speed sensor, generates an operation command based on the target corner, the target corner speed, the actual corner and the actual corner speed, sends the operation command to the motor, and rotates the motor according to the operation command to drive the steering wheel to rotate so as to achieve the target corner and the target corner speed in the voice command.
An electric power steering device and a hydraulic power steering device in a steering system are integrated together, and the electric power steering device consists of a power motor, a speed reducing structure, a torque and corner sensor, a torsion bar and the like; the motor drives the speed reducing mechanism according to the magnitude and the direction of the input current to drive the output shaft of the hydraulic power steering device to swing left and right, so that the steering of wheels is realized.
At low speed, the electro-hydraulic power-assisted steering system can provide larger steering power, so that the steering portability of the vehicle is ensured; when the vehicle speed is increased, the steering power provided by the electro-hydraulic power-assisted steering system is gradually reduced, and the steering force required by a driver during steering is gradually increased, so that the vehicle stability is improved.
The electric power steering system can apply certain additional aligning moment or damping moment, so that the steering wheel can accurately return to the middle position at low speed, oscillation and overshoot of the steering wheel in the high-speed aligning process can be restrained, and aligning performance of the vehicle at high speed and low speed is considered.
